(Phys.org) -- Virtual melting is a phase transition phenomenon associated with solid-solid phase transformation and relaxation of nonhydrostatic stresses and other effects in HMX explosives, as well as with crystal-crystal ...
Scientists have designed a simple system to study how electrons travel through energy barriers instead of over them.

If you are not a condensed matter physicist, vanadium oxide (VO2) may be the coolest material you've never heard of. It's a metal. It's an insulator. It's a window coating and an optical switch. And thanks to a new study ...
